I had my last baby flown in and brought the same things others mentioned - towels, baby wipes, water and pee pads. I also brought along a scissors - to cut the plastic ties off the crate, and chopped up pieces of Natural Balance roll. I took him directly to the bathroom and put the pee pad on the floor but he was more interested in sniffing around so I wrapped him up in a blankie and fed him a couple bites of food and he slept in the car the whole way home
